Insulator superconductor transition on solid inert gas substrates
K. Das Gupta, Swati S. Soman, G. Sambandamurthy +1
We present observations of the insulator-superconductor transition in ultrathin films of Bi on solid xenon condensed on quartz and on Ge on quartz. The relative permeability $ε_{r}…
Vortices and the mixed state of ultrathin Bi films
G. Sambandamurthy, K. Das Gupta, Swati S. Soman +1
Current-voltage (I-V) characteristics of quench condensed, superconducting, ultrathin Bi films in a magnetic field are reported. These show hysteresis for all films, grown both wit…
Critical currents and vortex-unbinding transitions in quench-condensed ultrathin films of Bismuth and Tin
K. Das Gupta, Swati S. Soman, G. Sambandamurthy +1
We have investigated the I-V characteristics of strongly disordered ultra-thin films of {\it Bi} and {\it Sn} produced by quench-condensation. Our results show that both these syte…
Vortex dynamics and upper critical fields in ultrathin Bi films
G. Sambandamurthy, K. Das Gupta, N. Chandrasekhar
Current-voltage (I-V) characteristics of quench condensed, superconducting, ultrathin films in a magnetic field are reported. These I-V's show hysteresis for all films, grown…
Possible robust insulator-superconductor transition on solid inert gas and other substrates
K. Das Gupta, G. Sambandamurthy, Swati S. Soman +1
We present observations of the insulator-superconductor transition in ultrathin films of Bi on amorphous quartz, quartz coated with Ge, and for the first time, solid xenon condense…
